我正在嘗試連接到數據庫,以驗證用戶使用Apache Shiro。我有一個servlet調用一個java類來執行這個任務。現在它只是簡單地改變一個字符串,如果它成功驗證。我已嘗試許多不同的連接方法:數據池,JTDS,Microsoft SQL Server的JDBC,所有給我的錯誤:Apache Shiro SQL錯誤,同時驗證用戶

SQL error while authenticating user [user1]

我的日誌文件也顯示此錯誤:

Warning: RAR5058: Error while Resizing pool SQLS1-TestBilling. Exception : Connection could not be allocated because: The TCP/IP connection to the host SQLS1, port 1433 has failed. Error: "null. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

我能在Servlet中使用TestBilling連接池就好了,所以我不認爲這是池的問題,但似乎無法使用ini文件聲明來使用SQL。有什麼我失蹤,忘記做,或做錯了?

以下是相關文件:

GetAuthServlet.java:

package com.phmc.shiro5web; 

import java.io.IOException; 
import java.io.PrintWriter; 
import javax.servlet.ServletException; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

public class GetAuthServlet extends HttpServlet { 
@Override 
protected void doGet(HttpServletRequest request, HttpServletResponse response) 
     throws ServletException, IOException { 
     response.setContentType("text/html;charset=UTF-8"); 
     PrintWriter out = response.getWriter(); 
     out.println("<!DOCTYPE html>"); 
     out.println("<html>"); 
     out.println("<head>"); 
     out.println("<title>Auth</title>");    
     out.println("</head>"); 
     out.println("<body>"); 
     AuthenticationClass au = new AuthenticationClass(); 

     String b = ""; 
     b = au.isAuthenticated("mmarino", "test"); 
     out.println(b); 
     out.println("</body>"); 
     out.println("</html>"); 
} 

AuthenticationClass.java:

package com.phmc.shiro5web; 
import org.apache.shiro.SecurityUtils; 
import org.apache.shiro.authc.*; 
import org.apache.shiro.config.IniSecurityManagerFactory; 
import org.apache.shiro.mgt.SecurityManager; 
import org.apache.shiro.subject.Subject; 
import org.apache.shiro.util.Factory; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 

public class AuthenticationClass { 
    private static final transient Logger log = LoggerFactory.getLogger(Authentication.class); 



    String isAuthenticated(String username, String password){ 
     Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini"); 
     SecurityManager securityManager = factory.getInstance(); 
     SecurityUtils.setSecurityManager(securityManager); 
     Subject currentUser = SecurityUtils.getSubject(); 
     String b = "fail"; 
     log.info("Test"); 
     try{ 
      if (!currentUser.isAuthenticated()) { 

       UsernamePasswordToken token = new UsernamePasswordToken("mmarino", "test") ; 
       token.setRememberMe(true); 
       try { 
        currentUser.login(token); 
        b = "Success"; 
       }catch (UnknownAccountException uae) { 
        log.info("There is no user with username of " + token.getPrincipal()); 
       } 
      } 
     }catch(Exception e){ 
      b = e.toString(); 
     } 
     ) 
     return b; 
    } 

} 

Shiro.ini:

[main] 
ds = org.apache.shiro.jndi.JndiObjectFactory 
ds.resourceName = jdbc/TestBilling 


jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm 
jdbcRealm.dataSource = $ds 
jdbcRealm.permissionsLookupEnabled = true 
jdbcRealm.authenticationQuery = SELECT theuser FROM UserList 
securityManager.realm = $jdbcRealm 

我也試過: jdbcRealm.authenticationQuery =選擇用戶FROM UserList where passwordList =?

在倒數第二行的Shiro.ini文件中。

連接池有多大? –

@BrianDemers你是什麼意思「多大」?現在我們仍處於測試模式,所以它沒有獲得很多流量,我可以告訴你。 –

沒錯,但是如果池真的很小,並且你有多個連接(一個來自Shiro,另一個來自你的servlet),它不會花費太多。您還正在爲每個請求創建一個新的SecurityManager。 我建議看一看Shiro [網頁示例](https://github.com/apache/shiro/tree/master/samples/web),或者看看[我們的應用程序文檔](http://shiro.apache.org/web.html)。我建議,作爲一個起點,一旦你有Shiro servlet過濾器設置和工作,添加你的自定義邏輯將會容易得多。 –

似乎有一個額外的錯誤,我沒有聽清楚造成log4j的突破,這是不被看到,呈現出基本的SQL錯誤保持了其他錯誤。

嘗試

# DataSource config 
ds = org.apache.shiro.jndi.JndiObjectFactory 
ds.requiredType = javax.sql.DataSource 
ds.resourceName = jdbc/TestBilling 
+0

我寄予了很高的期望,但我仍然因爲這種變化而出現同樣的錯誤。 :-( –
